Re: image problem in mpc 3500

Electrical surge can take out all the boards. I recommend you should order a new IPU and SBU. Although you can do a test on the SBU to see if it's still good.

SBU Test Mode
There is an SP code to create a test pattern which can be used as a diagnostic tool to
troubleshoot problems in the SBU:
􀂃 SP4907-001 SBU Pattern - Test Pattern
To print the pattern:
􀂃 Select the pattern to print.
􀂃 Touch "Copy Window" then press the Start key twice.
